Historic shipwrecks often evoke dreams of sunken riches waiting on the bottom of the ocean to be reclaimed.
The Kyrenia has a storied legacy as the first major Greek Hellenistic-period ship to be found, in 1965, with a largely intact hull. From 1967-69, it was excavated along with its cargo, which included hundreds of ceramic vessels, then reassembled offsite and scientifically studied. The first volume of the final publication of the Kyrenia ship project, released last year, argued the wrecking date was a little later, closer to 294-290 BCE, but the primary piece of evidence -- a poorly preserved, nearly illegible coin -- was not watertight.The biggest hurdle for accurately dating the Kyrenia has been another artifact, one from the 20th century: polyethylene glycol .
They used that technique to remove PEG from a Kyrenia sample that Manning and collaborators had tried, and failed, to accurately date 10 years ago. The team also now dated a tiny, twisted piece of wood that was salvaged from the Kyrenia in the late 1960s but was too small to be included in the reconstruction, thus avoiding PEG-treatment. It subsequently sat in a jar of water in a museum for 50-odd years.
